Nice, but don't you think that the Logo is a bit too streched?
You can also try to fit the Debian whirl with the border of the aptosid logo.
Another tip: Reduce the opacity of the Debian whirl so that it will more become a part of the background. Play around a bit with values like transparency, saturation and blur. If you don't use it already, I would recommend Inkscape for creating graphics like this. At first, it's not the easiest thing to handle with, but after a time you'll feel how flexible and powerful it is.
